The use of variants the gas metal arc welding (GMAW) process has become an affordable option in industry. Alternating current–gas (AC-GMAW) arises as one them, providing additional degrees freedom for controllability and versatility. This study focused on analysis a complex waveform AC-GMAW stainless steel, employed modern synergic programs, which not been widely disseminated technical literatu...

On-l ine quality control in automated welding operations is an important factor contributing to higher productivity, lower costs and greater reliability of the welded components. However, the development of on-l ine inspection techniques and feedback control is still in its infancy. Sound signature produced by GMAW contains information about the behavior of the arc column, the molten metal and ...

Abstract The study presents a data-driven framework for modelling parameters of hardfacing deposits by GMAW using neural models to estimate the influence process without need creating experimental samples material and detailed measurements. GAS Metal Arc Welding (GMAW) does sometimes create non-homogenous structures in not only deposited material, but also heat-affected zone (HAZ) base material...

Fusion welding of heat treatable aluminum alloys leads to a significant loss of strength in the heat affected zone (HAZ) due to overaging. This work was aimed to improve the mechanical properties of Al-6061 welds. Plates of 6 mm in thickness were solutionised at 530◦C for 1 h followed by water quenching and aging at 160◦C for times between 13 to 19 hours. Welding was performed with the gas meta...

The reconstruction of the geometry weld-deposited materials plays an important role in control torch path GMAW. This technique, which is classified as a direct energy deposition technology, experiencing new emergence due to its use welding and additive manufacturing. Usually, determined by computerised fabrication tools, but these software tools do not consider geometrical changes along case du...

Teknik pengelasan semakin banyak dipergunakan secara luas dalam proses penyambungan plat-plat besi, kontruksi bangunan dan konstruksi mesin. Salah satu metode yang sering dipakai, yaitu gas metal arc welding (GMAW). Tujuan penelitian ini adalah untuk mengetahui parameter terbaik pada Pengelasan GMAW terhadap struktur mikro, makro kekerasan Material ASTM A537 A653 DDS (galvanis). Metode digunaka...

This paper focusses on effect of flat wire electrode gas metal arc welding (FW-GMAW) inline during the process to improve quality weld bead. Since perimeter has enlarged, turbulence molten droplet characteristics is altered due electromagnetic force. To bring out, butt joint are proven with use electrode. The experimental results indicated that, and their orientations significantly factors bead...

As improving fuel economy and performance through weight reduction in vehicles are recognized as important tasks, the defense industry is researching ways to reduce of armor plates for combat increase bulletproof durability. Most manufactured using weld joints. High-hardness (HHA) used make plates; however, its mechanical properties deteriorate because hydrogen embrittlement high-temperature so...

Hybrid Layered Manufacturing (HLM) combines the benefits of both subtractive and Additive Manufacturing (AM). In this paper authors did characterization of AM components by using Kernel Average Misorientation (KAM), Electron Backscatter Diffraction (EBSD) and hardness tester. The main focus is on matrix integrity during Gas Metal Arc Welding (GMAW) deposition and surface quality during machinin...
